Final answer:
Epigenetic modifications that contribute to inheritance include DNA methylation, histone modifications, and chromatin remodeling.
Step-by-step explanation:
Epigenetic modifications can contribute to inheritance through changes in chromatin configurations. Three categories of modifications that can contribute to epigenetic inheritance are DNA methylation, histone modifications, and chromatin remodeling. DNA methylation involves the addition of a methyl group to the DNA molecule, which can influence gene expression. Histone modifications, such as acetylation and methylation, affect the structure of chromatin and gene accessibility. Chromatin remodeling involves changes in the packaging of DNA and can impact gene expression.
